Product Overview
The Rexroth MK 15 G14/V (Material Number R900423326) is a high-precision throttle check valve designed for modular hydraulic system integration. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this component functions as a dual-purpose flow control device. It combines a manually adjustable throttle for precise flow metering in one direction with a free-flow check function in the reverse direction. Engineered for sandwich plate mounting, it is typically installed between a directional control valve and a subplate, providing reliable speed control for actuators in demanding industrial hydraulic circuits.

Engineering Features & Advantages
- Precision Flow Metering: The valve features a fine-thread adjustment spindle that allows for sensitive and accurate setting of the throttle cross-section, ensuring precise actuator speed control independent of load variations.
- Integrated Free-Flow Check: In the reverse flow direction, the built-in check valve opens to allow unrestricted flow, minimizing pressure drop and preventing unintended throttling during return strokes.
- Modular Sandwich Construction: Designed for direct mounting between standard ISO/DIN interface valves and subplates, eliminating the need for additional piping and reducing potential leak points in the system.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, featuring a robust housing and hardened internal components for long service life and resistance to contamination.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring a drop-in replacement for existing Rexroth MK series installations.
Typical Industrial Applications
This throttle check valve is widely utilized in heavy industrial scenarios requiring precise speed regulation of hydraulic actuators, such as plastic injection molding machines, metallurgical presses, CNC machine tools, and general construction & marine hydraulics. It is particularly effective in circuits where a unidirectional speed control is required without the complexity of a full proportional valve system.
